Beitknown that I, bGEORGE A. LOWRY, a

citizen of the United States,residing at Chiment in Presses for Cotton, Wool, andthe Like, of which the following is a specification.

This invention relates to presses for cotton, Wool, hair, hay, and the like.

The object of the invention is to provide a press of novel and exceedingly simple con-A struction for pressing cotton, wool, hair, and the like into bales.

A further object of the invention is to provide means for absorbing the heat generated during the operation of pressing.

Af'rther object of the invention is to pro vide means for facilitating the delivery of the material to the press.

Other objects of the invention will'appear more fully hereinafter.

The invention consists, substantially, in the construction, combination, location, and relal tive arrangement of parts, all as will be more fully hereinafterV set forth, as shown in the accompanying drawings, and finally more specitically pointed out in the appended claims.

- Referring to the accompanying drawings and the various views and reference-signs appearing thereon, Figure l is a view in central longitudinal section of a press embodying the principles of my invention. Fig. 2 is a plan view of the cap-plate, a portion being in hori-V zontal section, illustrating the slots through which the material is tovbedelivered to the press. Fig. 3 is a side elevation of the capplate. Fig. 4 is a broken detailsectional View of the cap-plate on the line 4 4, Figs. 1 and 2. Fig. 5 is a view similar to Fig. 2, showing means for exhausting the air from the feed slots or openin gs `in the cap-plate, thereby creating a suction for facilitating the delivery of the material to be pressed therethrough. V Fig. 6 is a central transverse sectional viewof the construction shown in Fig. 5 on the line 6 6, looking in the direction of the arrows. Fig. 7 is a broken detail sectional view on the line 7 7, Fig. 6, looking in the direction of the arrow. Y

The same 4part is designated by the same reference-sign wherever it occurs throughout the drawings. y i I have Vshown my invention as applied to the type of press set forth and fullydescribed and claimed in my Patents Nos. 581,600 and 581,601, dated April 29, 1897, and wherein is shown and described a type of press comprising an open-ended chamber A and a cap-plate B for one end thereof, said chamber and capplate being mounted for relative rotation. For instance, in the particular form shown the chamber A is rotated through suitable gearing,while the cap-plate B is rigidly mounted upon the casing C. Any suitable gearing for relatively rotating the chamber and the cap-plate may be provided, as set forth in my prior invention.

Inasmuch as the present invention relates more particularly to the construction and arrangement of the cap-plate, I do not deem it necessary herein tolspeciically set forth the construction and arrangement of the other parts of the press.

In the operation of a press embodying the principles of my invention, and particularly of the type set forth in my before-mentioned patents, wherein the material to be pressed ,is subjected to pressure, a considerable degree of heat is developed by reason of the friction of the materialagainst the under surface of the capplate during the relative rotations of the chamber and cap-plate. In order to avoid excessive heating from this cause, I construct in my present invention the cap-plateB, with a raised peripheral rim or flange Dthereby forming a receptacle'in the top surface ofthe cap-plate, as indicated at E, `adapted to receive Water or other cooling agent, a circulation of which, if desired, may be maintained through such receptacle or chamber E, and, if desired, an overiiow-opening F may be provided, whereby such circulation may be maintained, as shown in Fig..l. ,By this construction I avoid `the vobjection ofexcessive heat due to friction developed during the operation of the machine.

I will now describe the construction of the cap-plate, whereby the delivery of the material to be pressed therethrough to the chamber A is facilitated In my before-mentioned patents I have shown a cap-plate provided with a single slot or opening therethrough and through which the material to be pressed is yintroduced to the press-chamber. In Sonie eases, however,.

of the pressing operation is accelerated. 'byi snpplyingto the 'press the prod-net f ioin several gins simultaneously, and in order to facilitate the feed of thevmaterial through' the 'eap-plate,1 provide said 'cap with a plurality of passages G, into each. of which one or' more gin's may deliver and each of which inturn opens into the pressing-chamber Ain a 'inann'erf Similar' to the opening through thecapplate in my prior application. Thus it will be 'seen that; provide a construction of cap adapting each vpress to be supplied from a bank of 'several gins simultaneously, and 'sincethe speed of compression `of the bale is dependent inoie oi1 less upon the rapidity of feed of material to the press it will be 'seen that I provide a construction wherein the work of effecting a compression of the inaterial into bale form'is accomplished rapidly `and eiiieientl'y.

It is a coininon practice to deliver the lintcott'on from gihs by inea-ns of a forced airbl-ast. l If, however, such blast deliveied the lint- 'cotton into a closed cha1`1iber-'su`ch, for instance, as the passages G'of the cap-plateeiici'ency of the delivery of the' material to be' pressed to the chamber A is' materially decreased by reason of the fact that such aiiis'not provided with an outlet. In order to ,lmv' this abject-i011 and. t0; provide an are" rangement wherein the lint cotton is relieved of the pressure of theyforee'd draft .within "the passages G ,wliereby the material tob'e pressed be efficiently Ydelivered through the def 'pr'o'vide suitable openingsH J through the walls of such passages G, through which the forced' air-blast Vof the gin-feed may readily @50meof the delivery of the material through the passages G,'I may, if desired, attachra suitopenings' thevair of the gin blast-feed, which passages.-

In 'order to increase the -efliciency l my invention 4effective for drawing the material tothe delivery end of the passage G, I arrange said openings I-I J or one of them in as close proximity to such delivery end of the passage as may be-possible, as clearly shown, 'whereby the cotton is drawn as nearly as possible tov the point of delivery to the pressingchamber, and hence, if desired,.I inay omit the openings H J Inorder'to prevent the material delivered to the press from being drawn through the openings H J and connections K, I arrange asuitable gauze or netting over said openings, as clearly shown.

While the features of my invention, as above explained, are applicable to any suitable or desirable construction. of cap-plate, I have shown saidl features applying to a cap- ,plate wherein the inner side thereofthat is,

the side thereof which projects into the open end 'of chamber A-is 'provided 'with aj surface which. 'projects to 'an increasing" depth 'into the chamber, as more particularly set forth in my before-mentioned application, and whereby the feed of the material is fa- 'cilitated by reason of the fact that the delivery-mouth 'of passage G ifs formed oftwo lips, one of which-namely, the inner lipL-operetes in the lower plane, and the point of the other oigfar lip is at M, Figs". 4 andv 7.

In order that the material may te delivered to the chamber at apoint in line with the inner surface of such chamber, I preferably forni a peripheral groove in the u' ppen inner edge of the `charnbe'lf, asindiieaied at N, Fig. l, and I extendA the portion 'of the cap-plate which ft's over the open end of the chamber to a point enabling it toventer or' be received in the groove N, as clearly shown in Fig. l, whereby theouter edge of the passage G delivers into the chamber at least in line with or outside of the inner surface of theend of the cht't'mloer.Y Thus the material isdelivered to the chamber at a point-such that it will engage or ride ag'z'tinstk thev inner wall of the chamber from tnetiine it is' delivered to the machine. T ljiisl have found to be a benencial feature, for the reason that in the c'ase of rotating the chamber-A instead of the capplate the holding of they mass of material con 4tained inthe chamber stationarydnring the i rotation of suchchainb'e'r is avoided'.

livery mouth or 'opening of such passages/I j Many variations and' changes' in the details of construction, location, and arrangement of partswould readily suggest themselves to peri sons skilled. ini-,lie en: end still fel-i 'within the spirit and scope of lnyinven'tion. I do not desire, therefore,` to be limited or restricted tothe exact details of construction and arable fan to the connections K, which 'coinmunicatewiththe openings HJ, whereby a suction or edict-ion is lcreated. through the i openings H J, thereby drawing through such rangement shownan'd described; but,

'Havingn'ow set forth the object andnature of my invention anda form of apparatus embodying the saine and having explainedthe constructiomfunction, and mo'deof operation tends to create a vacuum within the kpassages G, whereby the material is drawn throughv thejpassagesG to the deliveryend of such In order to make this feature of thereof, Awhat I 'claim as newv and useful and of myown invention', an'd'de's'ir'eto secure by Letters Patent, is;
